一年一度的诺贝尔奖已逐一揭晓，又一次引起了世人的关注，不过提到搞笑诺贝尔奖，恐怕知道的人并不多。该奖是对诺贝尔奖的有趣模仿，其名称是对Ignoble和Nobel Prize两词的谑称。该奖的颁奖仪式于每年十月在诺贝尔奖颁奖前一至两周举行，其目的是选出那些“乍一看好笑，后又发人深思”的研究。今年的搞笑诺贝尔奖一如既往地传承了其幽默风格：空酒瓶打人杀伤力更强、胸罩可改为防毒面具、从熊猫粪便中提取细菌减少厨房垃圾等，可不要被它雷到哦。

Background: Hypothermic preservation of boar semen is considered a potential method for omitting antibiotics from insemination doses, thereby contributing to the global antibiotic resistance defence strategy. The main challenges are chilling injury to spermatozoa and bacterial growth during semen storage leading to reduced ***: To examine chilling injury and the number and type of bacteria in boar semen stored at 5 ℃ in the absence of antibiotics, and to assess the applicability of hypothermic semen storage under field *** and methods: Boar ejaculates were extended with AndroStar~? Premium, stored at 17 ℃ with and at 5 ℃ without antibiotics and tested for functional sperm parameters by flow cytometry. Raw semen and extended samples were investigated bacteriologically. Fertility was evaluated after once-daily inseminations of 194 sows in a field ***: Lethal sperm damage assessed by motility and membrane integrity was low throughout storage in both experimental groups. Sublethal chilling effects based on the decrease of viable spermatozoa with low membrane fluidity were higher(P 0.05) between sow groups inseminated with semen stored antibiotic-free at 5 ℃ and semen stored at 17 ℃ with ***: Despite subtle chilling effects and low bacterial numbers, antibiotic-free hypothermic storage of boar semen offers the possibility to reduce the use of antibiotics in pig insemination.

Open Journal of Forestry 2014年第2期4卷 106-111页

The management of second-growth Sequoia sempervirens (coast redwood) forests for the purpose of restoration and ecological conservation is a growing trend. However, little is known about the long-term regenerative potential of this forest type in the absence of post-harvest management techniques such as thinning and planting. Data on forest composition and structure were collected on a chronosequence (80 - 160 years) of mature recovering stands in the southern coast redwood range using a replicated, randomized, plot design. Results indicated that many stand characteristics including tree density, canopy cover, redwood dominance, species richness, herbaceous cover, and shrub cover reached levels statistically equivalent with old-growth reference sites in recovering stands within the time frame of this chronosequence. The recovery of individual herbaceous understory species was inconsistent however. While the cover of redwood-associated species (Oxalis oregana, Trientalis latifolia, and Disporum hookeri) reached levels statistically equivalent to old-growth reference sites, others (Trillium ovatum and Viola sempervirens) did not. Total basal area and species evenness also trended toward, but did not reach, old-growth conditions. The arboreal aspects of coast redwood forests appear to be remarkably resilient following a single logging event, and recover rapidly in the absence of active restoration techniques. The protracted recovery of certain redwood associated herbaceous understory species will require further study.

国际捕鲸委员会成立于第二次世界大战之后,最初的宗旨是有效利用鲸鱼资源。但是随着鲸鱼种类的濒临灭绝,1986年,该委员会做出决议,禁止对这一海洋哺乳动物进行商业性捕猎。随着执行保护措施后鲸鱼数量的增加,捕杀与保护之间的矛盾有所激化。能否在商业利益和动物保护两者中间找到一个平衡点呢?To kill,or not to kill,that is a question.
